(No modelJ To aZZ whom it may concern.-

Be it known that we, LOUIS ALBERT PERROT and HARRY WALLACE WVARRINGTON,both of Richmond, in the county of Henrico and State of Virginia,haveinvented a new and Improved Rotary Engine, of which the following isa full, clear, and exact description.

The object of our invention is toprovide a new and improved rotaryengine which is simple and durable in construction, very effective inoperation, and easily reversed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a side elevation of our improvement with part of the headbroken out. Fig. 2 is a vertical cross-section of the same on the linesa: a; of Fig. 3. Fig. 3 is a central sectional elevation of the same onthe lines 3 y of Fig. 4. Fig. 4 is a sectional plan view of the same onthe lines o z of Fig. 3.

On the cylinder A, of suitable size, are secured the two heads B and O,in which is mounted to turn the main shaft D, on which is secured thewheel E, fitting in the cylinder A between the heads B and O.

In the rim of the wheel E are formed the cross-buckets F, open at theouter ends and closed at both sides of the rim, and separated from eachother by the radial partitions G.

One side of the cylinder A is extended outwardly, forming the offset H,in which is held to turn the valve I, provided with the opening J,adapted to connect the steam-inlet pipe K with either the channel L orL, each leading into a recess or groove, N or N, respectively extendingfrom the said channels L or L in opposite direction to the other side ofthe cylinder A, and terminating a short distance from each other, asshown in Fig. 3. In the valve I is also formed the opening 0, leadingfrom the exhaustpipe l? inwardly, and being adapted to connect witheither channel L or L. On the valve I is secured a handle, Q, forturning the valve I so that the openingJ con nccts the steanrinlct pipeeither with the channel L or L, while at the same time the exhaust-pipel? is connected with the channel L or L, respectively.

In each of the heads 13 and O is formed an annular groove, R, in whichis held a packingring, S, adapted to be pressed against the face of thewheel E by set screws T, screwing in the said heads B and C from. theoutside and butting with their inner ends against the rings S. Thehearings in the heads B and G are provided with suitable oilers, tolubricate the main shaft D.

The operation is as follows: When the valve I is in the position shownin Fig. 3, then the steam, entering the inlet-pipeK, passesthrough theopening J in the valve I and passes into the channel, from which itpasses into the groove N and into buckets F in the wheel E, which isturned in the direction of the arrow 0. by the steam pressing againstthe partition G in the direction of the arrow a. 'W hen one of thebuckets F passes the end of the groove N, then the pressure of the livesteam supplied by the pipe K and the groove N is shut off, and when therespective bucket opens, on the further rotation of the wheel E, intothe groove N, then the steam in the bucket F es capes and passes alongthe groove N into the channel L, and finally escapes through the opening0 in the valve I into the exhaust-pipe 1?. When the operator desires toreverse the engine, he then turns the valve I by means of the handle Q,until the opening .I connects with the channel L, and the opening 0 thenconnects with the channel L. The steam from the inlet-pipe K then passesfirst into the channel L and the groove N, and acts on the partitions Gin the opposite direction,as before described, thus reversing theengine. The steainthen e hausts through the groove N, the channel L, andthe opening 0. r

The inlet-pipe K can be closed by the valve I by turning the latteruntil the openings J and 0 do not connect with the channel L and L andthe pipe K.

Suitable means can be employed to hold the valve I in a locked position.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is== 1. In a rotary engine, thecoinbinatiomwith a cylinder, of a wheel having buckets in its rim andseparated from each other by partitions, the said wheel fitting in thesaid cylinder, a shaft carrying the said wheel and mount ed in the headsof the said cylinder, an exten sion formed on the said cylinder andhaving channels leading in opposite directions to the said buckets inthe wheel, and a valve held in the said extension and provided withasteaminlet opening and an exhaust-opening connecting with the saidchannels, substantially as described.

2. In a rotary engine, the combination,with a cylinder having thegrooves N and N, of a wheel having buckets in its-rim and separated fromeach other by partitions, the said wheel fitting in the said cylinder, ashaft carrying the said wheel and mounted in the heads of the saidcylinder, an extension formed on the said cylinder and havingtwochannels extending in opposite directions and opening into thegrooves N and N, respectively, avalve held in the said extensionandprovided with asteaminlet opening and an exhaust-opening arranged toconnect with the said channels, a steam-inlet pipe connecting with thesaid inlet opening of the valve, and an exhaust-pipe connecting with oneend of the exhaust-opening in the said valve, substantially asdescribed.

3. In a rotary engine, the combination,with aeylinder having the groovesN and N, of a wheel having buckets in its rim and separated from eachother by partitions, the said wheel fitting in the said cylinder, ashaft carrying the said wheel and mounted in the heads of the saidcylinder, an extension formed on the said cylinder and having twochannels extending in opposite directions and opening into the pipeconnecting with the said inlet-opening of the valve,and an exhaust-pipeconnecting with one end of the exhaust-opening in the said valve, andmeans, as described, for turning the said valve, as set forth.

4. In a rotary engine, the cylinder A, having the grooves N and N,leading to the channels L and L, the extension H, in which the saidchannels L and L are formed, the valve I, having the openings J and 0,adapted to connect with the said channels L and L, the steam-inlet pipesK, adapted to connect with the said opening J, and the exhaust-pipe P,adapted to connect with the opening 0, in combination with the wheel E,having the buckets F, separated from each other by the partition G, andthe main shaft D, carrying the said wheel E and being mounted in theheads of the said cylinder A, substantially as shown and described.
